Introduction

This document provides the memory map and locations of reference materials for those who wish to add additional hardware to their NetBurner device.

SBE70LC Processor Information

The SBE70LC uses the Microchip ARM SAME70 microprocessor. The reference manual and datasheet provide in-depth information on the processor, including register settings, bus configuration and timing information. It is located in the <nburn_install>\docs\Arm directory of your NetBurner installation.

Datasheet

The datasheet for the SBE70LC module includes information on connectors, signal names, and operational parameters. It is located on the SBE70LC product page: SBE70LC Datasheet.

Development Board Schematic

The SB70LC-ADPT-100 development board schematic is located in the <nburn_install>\docs\NetBurner\platform\Schematics directory. This schematic can be used for design ideas in your own hardware implementation for power, RS-232, RS-485, and SD Flash card implementation.

Memory Operation

The SBE70LC uses 3 types of memory:

• 2MB Flash memory for non-volatile system configuration storage, user application storage, the application in a compressed format, and the optional EFFS-STD file system (note this is different from the EFFS-FAT flash card file system).
• 8MB SDRAM containing the uncompressed application as well as any application data.
• 384KB on-chip SRAM located in the SAME70 microprocessor.

At power-up the application is decompressed from Flash memory to SDRAM and execution begins. If the application is continuously trapping the device can be recovered using the jumper recovery method as described in the Recover section, or if you have serial communication enabled the boot sequence can be aborted by sending the appropriate serial command when prompted after a power cycle.
